Cosworth Co% level,help please
The level at idle won't come down below 9%,had m8 check it last week and would'nt go below 10% so fitted a new coolant temp sensor as the screw on ECU did'nt make any difference to levels
Have been told you can reset the mixture screw pot by turning screw 4 turns in then 4 turns out then 2 turns back,supposedly this resets it???
Could this be a chip problem,or is there anything else I can check/replace that would affect fueling?
Any help appreciated

are you sure there isnt a brake in the wires going too the coolent sensor?
i can tell you the pins if needed so you can measure the resistance with a multimeter!
is the engine hot enough? has the fans come on?

DazCoes the MAP sensor affect the fueling on tickover?
If so have got a spare 3-bar so could try that!

Tryed diffrent MAP sensor,no joy
Found fuel press reg was'nt working as it should be,took vac pipe off and pressure
did'nt rise!
Could have been costly on a long flat out blast
Got a chip on way so going to try that(cheers RS Gus)

Mines sorted at last
Back on the road
It was the ECU that was fooked in the end,thank you for everyones input
Bought myself a multimeter and checked all resistances on sensors and earths etc on ECU plug,meter was £8,well worth the money
Thanks also to MSD,very helpfull and freindly advice over the phone
